kill -INT $$ only stops the script while nothing traps INT. Add a cleanup trap on INT - a normal thing for a script to do - and bash runs the handler and resumes at the next statement, so a guard prints its error and the script carries on to exit 0. exit 42 cannot be declined, and the EXIT trap still cleans up.
